Application filed April 12, 1920. Serial No. 373,353.

To all whom it may concemi Be it known-that I, Swnnnr Mor son, a citizen or" the United States, residing at Fowler, in the county of Otero and State of.

Colorado, have invented a certain new and useful Improvement in Checkrow Planters,

of which the following 1 specification.

My invention relates to lmpr l 1n i check rower planters.

One of the-objects of my invention is E o provide novel check row marking means. further obj ect of my invent on 1s the provision of means by which the marking means operates seed dropping use ofa cable. v

A further object of my invention means without Y the dropping mechanism and with fthe' use of which the distance between the rows. may be varied. 4 1

' Myinventionprovides still" further means by which the ground marking devices may be lifted clear of the ground. v

Mylinvention provides still further novel resilient means for forcing themarking into contact with the ground whereby amarking device of relatively light weight, vcan be made to make distinct markings on the ground.

The novel hereinafter fully described and claimed.

In the accompanying drawings, which. 7 illustrate the preferred embodiment of my invention, I

1 designates a frame of any suitable type supported on an aXle2, on which are rotais the provision of an expanslble and COIltI'EtOtlblfl rmarking wheel; arranged to operate seedfeatures of my invention are.

the or a.. spoked tably mounted two wheels .3," having. the

usual concave tread and adapted to travel respectively in the rear .of twoplanter shoes 4, which are of the'usual-type. Each 10f the wheels :8 is mounted between two collars 5, which are longitudinally adjustable on th v axle 2, to which they, are secured by set screws6, whereby the wheels 3 maybe adjusted'toward and from each other in a well .having securedto it a member13, having radial spokes 14, Fig. 6, whichare adapted 7 to be'engaged by radialspokes'15, of a spoked member 16, Fig. 7 and Fig-'8, which is secured rigidly to the intermediate portionof a rotaryjshaft 17 which is rotatably mountedin bearings18 which are supported by the frame 1. y .The shaft 17 is disposed transversely and has its, ends respectively connected by universal joints 19,-with--two end extensions20, which with the intermediate portion 17 form a fiexibleshaft The central portions 21, of two eXpansibleand contra ctible marking wheels are. -re-- spectively rigidly and longitudinally adtensions 2Q. i i 1 Raclially I adjustable in the central portion of each wheel-21,;Fig. 4;, are radial substantially T-shaped'members 23, the arms of each of which areldisposed transversely. Set screws 241 mounted in the central portion.

I 'justably secured by set screws 22 to the ex- 21 respectively-securethe members 23 in their adjusted positions. Radially ad justable in the laterallyextending arms of some of the members 23Yare-the stems 25- of disk marking shoes 26. which are arranged in pairs'and' are adapted-to make impressions the igroundifor the fpurposei-jof.

check'rowing. The shoes of each pair are .inthe sameradialplane, The stems 25ers. adjustably secured by means of set screws 27. :The central portion of theouterv end ofeach member 23iisj provided with acon'i cal; projectionQS, whichis adapted to; enter which in turn are supported by the frame 1.

I The boxes 29 are respectively supportedby flexible means, such astwo chains'32, which are respectively supported by two cranks 33 provided respectively at the endsrof a "transverse horizontal rock shaft 3 1 oscillatively .mounted in 'b6t11ll1gS 85 supported by the frame 1. Theroc'k shaftBe has a crank 36 to whichispivoted the forward end of aconnecting rod 37, the rear end of -which is pivoted to a lever 38 pivoted to the frame 1, and adapted to have locked engagement in the usual manner with a ftoothedquadrant 39 supported on the frame 1. By pulling thelever 88 rearwardly the boxes 29 may be lifted by means of the 'rod 37,-rock shaft 84cand chains 32.

liespectively encircling the chains 32 are two coil-compression springs 40, the lower ends of which respectively bear against the looxes29, and the upper ends of which bear respectively against the cranks 3'? When the lever 38 is thrown forwardly, the cranks V 3 3 will force the springs downwardly, thus 'forcin'gdownwardlytheboxes 29 and withthem the extensions 20 and marking wh-eel's 21. 'By the use of the springs 40, -much weight may beeliminated in the wheels-"21, while at the same time afi'ording means by which the "shoes 26 can make easily seen markson the ground. a

'In-erderthaetheshaft 17 may berotated by hand to properly set the -wheels21, without moving the planter, when the wheels Y 21have'been lifted 'frolnthe ground, 1 secure to said shaft'1'7 a hand wheel 41, Figs.

"1,2 and-'3,

Fo 'r' lift'ing the rear ends of the shoest,

I .there is extended through said shoes a'trans- "verse bar 12 to which is secured an arm 43, the upper end of 'which'is pivoted to an arm 44 of a bell crank lever 15 piyotally mounted on the rock shaft 34-, and the other arm 460i whiclris pivoted to the forward:

, 'end ofa rod 4 7, the-rear endofwhichis [pivoted to a leveretS mounted on the frame ""1 and ada Jted tohave locked en a ement *finthe usual manner with a toothed quad rant'49 mounted on the ffra'mefl.

' In-theoperati'onof my lIlVlltlOl'l, the

' partsiheing in the positions "shownin' the drawings; x -hen the mach ne: is moved forwardly, the marklngwhe'els 21 will-be 1 revolved, thereby rotating the shaft 17 and operatingthe seed-dropping-mechanism, as already described; 'At the same time the marking "shoes 26 will mark the ground,

each marking wheel making two sets of im- :pressions at opposite sides of the wheel. At the ends of the rows planted, the machine is turned around and is drawn in the opposite directiom-the shoes26 of the right wheel2 1 being made totra'vel in the marks madein the ground by the shoes 26 of the right ,wheel 21 or vice versa, depending upon the-turn being made to the right or left at the end of the row. It the shoes 26 do not register with the marks made on the last tripaeross the-field, the'lever 38 is 'operatedto lift the wheels 21, ;and thehand wheel 11 is used toturn" the shaft 17, so'as marks. The 'leyer 38 is then thrown forw'ardly upon w'hieh the springs 10 willjtorce the marking wheels 21 downwardly against the ground. Thefmaehine' maynow be moved forwardly across the field in the operation of planting. At any time when the shoesof the checking wheel 21 do not register with the marks with which they are designed to register, the machine is stopped, the lever 88, thrown'rear'wardly to properly position the shoes '26'with such;

:to lift the shaft 17 and the marking wheels 21, and the hand'wh'eel eel-operated to turn the shaft. l'l' to properly position the marking wheels.

By loosening the set screws 22, the mark ing wheels 21 may be adjusted toward or from each other on the shaft extensions 20 to correspond with any change OlEELdjuSb'. I

apart the pair -of shoes 26 to the distance required between the hills to be planted. ns theseed droppingmeehanism is dependg ent upon the revolving of the marking wheelsQl for its o eration, the'seed will be dropped from the boiies 7 at the proper times, the'hillsbeing farther apart when the wheels are expanded',- and nearer together diameter and circumference.

for the reason that in drilling, o ne set-cf shoe markings may be'covered -with dirt.
